PCR and ELISA

Oct 23, 2011

I had intercourse sex with sex worker in protected sex and unprotected oral sex. Last day I came to know her suffering from HIV Positive. Hence after 14 weeks I went for TRIDOT test, it came as negative, and after 17 weeks I took ELISA test and it was also negative. And also After 20 week I went for TRIDOT and it came as negative. Today I took PCR DNA test and result came as Not detected.
Please suggest what will be the next step? Am I safe from HIV?

Hi and thanks for posting.

We will answer these questions on this forum from time to time with Dr. Bob's passing. [Please note that not all "do I have HIV?" questions will be answered]

You have been tested multiple times with highly sensitive tests. A negative test at 12 weeks is pretty darn accurate. Multiple negative tests thereafter, including a DNA PCR? You're negative. If you really don't trust the multiple results, why get tested in the first place? If you really wanted to be sure, a negative screening test at 6 months (26 weeks) after your last risky exposure is the end-all, be-all statement.
